ELECTRIC IIEA1ING DEVICE.

Application filed April 6, 1908.

T0 aZZ whom it may concern:

Be it known that I, WILLIAM O. MORTEN SEN, a citizen of the United States, residing at Salt Lake Ci ty, in the county of Salt Lake, State of Utah, have invented certain new and useful Improvements in Electric Heating Dcvices; and I do hereby declare the foliowing to be a full, clear, and exact description of the invention, such as Will enable others sl:illed in the art to Which it appertains to make and use the saine.

This invention relates to certain new and useful improvemcnts in heating urns.

.lhe object oi 1ny invention is, to proVide an urn c mstructed so that a liq nid contained therein1nay be kept at a desired temperatnre.

In the accornpanving drawings I have shown in Figure 1 a perspective view of an urn embodying n1y invention with the lid partly opened. Fig. 2 is a botton1 view. Fig. 3 is a vertical section, and Fig. 4 is a horizontal scctional view, of an urn embodying my invention,

This invention relates to an elcctrically heated urn in Which certain beverages such as tea, colee and the like, may be kept at a certain predetermincd temperature, so that the liuid may be drawn from the urn, at all tinies at the desired temperature, the device being so constructed that the temperatnre of the urn contents may be raised or lowered.

In carrying on 2 the airn of my invention, I cmploy a cylindrica vessel or receptacle 5 pro vidcd abme with a l id 6 supported by means 0l. a bingo 7. This vessei is provided With the bottom 8 and the outwardly flared base fiangc 9. Tlris base flange at its forWard ripper odge is prmxidcd With the slot 1.0. li" id within this recentacle is an open ended cylinder l2, this cyiinder being secured to the l ottmn 8 disclosed in Fig.

Near its uppcr end the urn is provided with the spout 14 covered by means ci a suitable lid 15 and it is through this spout that the urn is filled when the lid 6 is closed, this lid being provided with the clasp 16 to properiv retain this lid. Held within the cylinder 12 which forms a hot air chamber are the two lan1p supporting bars 20 and 21, the lower bar being provided With the Jamps 22 and 23 While the upper bar is provided with the lamps 24 and 25.

lhrongh the central portion of the bottom 8 is formed an opening 26 through which pass Specification of Letters Patent.

the circuit wires including the individual fceders 30, 31, 32 and 33 and the common re* turn 34. The wires 30, 31, 32 and 33 are connected respectively With contact points 30, 31, 32 and 33, while the common return 34 is connected With the binding post 34 to which is also connected a leading in wire 35. A second lcading in wirc 36 is con nected with a binding post 37 to which in turn is connected a wire 38 leading to the pivot 39 and a switch lever 40 having an en larged head 41, said switch bei11 so pivotcd that it may be swung to engage its head with the contacts 30, 31, 32 and 38 successively, the head being of suflicient breadth to e11gage the entire number of contacts at one time, thus to ont one, tWO, three or the entire nu1n ber of la1nps into circuit with the leading in wires. Thc leading in wires pass through an opening 42 conveniently formed in the flange 9. Thns, it will be seen that there is provided means for contributing a varying degree of heat to the apparatns.

Communicating with the interspace between the body 5 of the urn and the interior cylindrical wall 12, is a common form of gage glass l3 While a thermo1neter 44- is disposed with its lower bulbed end projecting inwardly through the wall of the body 5. A faucet 45 is rovided for drawing oi the contents of the iiquid heat chamber or intcrspace between the walls above referred to.

VVhat is claimed is- An urn of the class describcd, comprising a cylindrical vessel having a lower slotted flange, an open ended cylinder secnred to the bottorn of said vessel to form a heating chamber, a lid to close said vessel and chamber, an upper and a lower lamp supporting bar within said chamber, electric lamps cured to said bars, a switch pivoted to the under-suriace of said urn having an operating handle extending through said slot, an elcctric terminal for each la1np in the path of said switch, conductors connecting said iamps and tern1inals, and conductors within a suitable circuit connected to said la1nps and switch ail. arrangcd as set :Forth.

In tes timony Where0f, I aflix n1y signature, in presence of two witnesses.

WILLIAM MORJENSEN.
